Opinions wanted about about major updates and those who maintain survival worlds

So I came late to the Minecraft game after my 7 year old got me into it a year ago. As a result, the village and pillage & bees/fox updates are the only ones we’ve experienced. I also know that updates only affect unloaded chunks. When the village and pillage update came out, there was still a significant amount of unloaded chunks nearby so it was super easy to adapt. When the last update came, it took us a little longer to find bees and a foxes since we now had to travel much further to discover unloaded chunks.

I’m so freakin excited about 1.16 but wonder if it’s worth starting over for. I’d say we have at minimum, a 3x3 (9 maps total) fulled zoomed out maps worth of chunks loaded. Then parts of maps further out. We also have a nether highway that takes you 25,000 blocks away and we have about 2 fully zoomed out maps of chunks loaded there. Of course there is still plenty of room to explore, especially if I build a new nether highway, but it also kinda bums me out that I’ll have to travel a distance to experience it.

So for those of you that have played survival through major updates, do you find it more enjoyable to expand your current survival world or do you prefer to start over?
